Here's another study showing that in just 30 days of eating fastfood this causes the liver enzymes that cause non alchohol fatty liver disease to be extremely elevated after the study subjects were told to eat 2 neals a day from McDonalds, Burger King and/or other fast food establishments.
One thing that did do well was the HDL went up but it's believed the high fat in the diet did this.
